Walking is a full body movement, the only thing that seems to be moving in your animation is the backward leg, Also visually the back leg in the animation is still the same as it was just a few pixels smaller, shade of the leg would come into play also the shin itself would not change size, you have to show it fading in the movement by the perspective, but be sure to watch the video, you will get it trust me.
